This invention Irelates to improvements in planes and particularly to that type of plane in which the blade is thin and flexible and is double edged, 'such as safety razor blades 6 of a common type. n A f n l l 'An object of the invention is to provide atool of the class above mentioned, which shall be efficientand durable as a'fplane, but of extreme simplicity in construction land cheap- 10 ness as to manufacturing cost. v

A further object is'the provision of a tool of the class mentioned, which 'shall have a minimum number of parts, lir'icluding a stock so desivned that the same may be kstamped 15 fromatingle piece of metalj I Af further object is toprovide, in such a tool,improved, simplified, compact, and eliicient adjusting means. I Y l ,A further object yis the provision "of al plane havinga stock with an arched orrecessed central portion and alsothe provision of a comparatively narrow tail portion. f Iam aware of the use of'safety razor blades in planesrof substantially conventional *1design, but such planes,'when r adaptedv forusing thinfiexible; double edged bladesfare comi vparatively clumsy, heavy and complicated in design, involvingnumerous parts andcompartively large expense for manufacturing. The :present 'invention provides as a plane adapted forusino` "such a blade, 4a tool that is light, handy, simple, involving the miniL mum numberof Darts and the minimum of expense in manufacture; With these andother objects in view,all of which willV more: fully hereinafter'appear, the invention comprises 'certain l novel constructions, combina'tions'and arrangements of parts more fully described and defined in the following specification and claims, and illustrated in ther` accompanying @drawings in which like refcrencecharacters indicate cor- 'respondingr parts "throughout andl in which:

Figure IVy is akplan of plane turned bottom up. 1 A IFigure'V is a section on line 5&5 of Fig. IIFigure VI is a section Online (5j-6 of Fig. 55 My invention comprises a stock, which may be stamped from a single piece of metal, consisting of a'heel piece l, a toe piece 2, and a central fiat sided' arch, having flattened 60l sides 3 and l, which form seats respectively for: the handle 25 andthe blade 6. 'The stock is also preferably provided with side guides and stiifening members 7. The forwardportion ofthe stock is preferably about the width 65 of the blade to be used,-while the edges of sid-e 3 converge and mergefinto the heel piece l which is narrower than the forward portion, allas clearly shown at Figs. I and IV.

YThe'toe piece 2 is provided with a'slot' 8 to 'I0v permitwthe edge of the blade 6 tofproject through the toe piece in the' manner usual in v planes. The seat 4 is provided with aper-r tures 5, so positioned that whenthe safety razor bladewith'theusual apertures therein, 7 5, as in the well-known Gillette razor blade, is placed'upon the seat 4, two of the holes'in suc'hblade willkliewithin the area of the apertures .5` for the; purpose hereinafter described.'` f' f The seat 3 is provided with an aperture 9 to accommodate the combined' handle securing means and adjustment means hereinafter described. 1 A, l

A clamp plate '10 is provided having aper- 85 tureslll alignedwith the holes in the razor bladeand having asliding fit between members 7 which yact as guides for the plate 10.

The-securing'ofthe blade to the seat l-an'd Y tothe.,adjustmentmechanism hereinafter de- 90 `scribed is accomplishedA` by a fork 12, providedv with threaded lugs 1.3, adapted tO pro-V ject upwardly throughthe apertures 5, the aforesaid holes in the blade and the apertures 1l in the clamp plate l() and thereabove to be 95 engagedby thumb nuts 14 by means of which thumb ynuts the clamp vplate 10 may be forced downwardly, thus clamping the blade securely against seat 4. Y

o The fork l2 is rigidly attached to the shank 1N.

(ifi

15, threaded into a. sleeve 16 slidingly and revolubly fitting within bushing 17, extending centrally through the handle 25 and through the aperture 9 in seat 3 against the underside of which seat the bushing may be riveteduor fiimpyd as at 18. The outer end of the bashing is threaded to receive loclrnut 19 for securing handle 25 firmly againstslianl andithereby` through the fork 12,

move the blade 6 forward and down, projecting it beyond the under face of the toe piece 2.* whileIthe reverse rotation of the sleeve 16 willretract the shank 15 and with it the `fork l 12Aand 'blade 6, and that by this simple means the extent of the projection ofthe cutting edge below the under face ofthe plane may be regulated "or adjusted.

It'will beunderstood that the surface of the 3@- fhnh I2 contacts with the under side of seat 4 wherebygjwhen the thumb nuts 14 are screwed dovmj the` seat4 and clamp plate 10 with the intervening blade 6 will be clamped securely together: thus holding the blade 6 in that posif tion to 'ulrich it has theretofore been adjusted.

For subsequent adjustment of the blade the thim'ib'nufts 14 will-be slightly loosened, thus permitting operation of the adjustment mechanism above described.

A's hereinabove indicated and as clearly shown? at'Fig. IV, the apertures 5 in seat 4 areelengated. The threaded lugs 13 lit snugly in the holes in the blade and have a sliding tibinithe apertures `5, thus permitting the slidw ing movement of the lugs 13 within theapertures 6 for adjustment of the blade.

For convenience in carrying a supply of bldesthere may be seated on the heel plate l beneath the handle a box 22 of suitable size for the reception of the blades. A spring retaining member 23 attached to heel piece 1 is provided for normally holding reserveblades'securely within the box while permitting easy removal thereof.v and also for retaini ing box 22 inposition by depressing it so that tent 24 in the bottom of the box will beheld myielding engagement with depression `24a in the heel piece 1.

1Blade' 6 may be readily removed forreplacement or sharpening by removal of the thumb n'uts 14 and the clamp plate 10.

It will be Anoted that theprovision of the seats 3 and 4 and the angular recess therebetween not only permits the use of stamped sheet metal for the stock and the positioning of all of the adjusting apparat-us within said recess and the handle, thus further simplifying the structure by eliminating the numerous and complicated parts of adjusting mechanism common in planes, but said recess together. withthe narrow rear portion of the stock also permits the use/of the plane in a varietyof positions, for chamfering and for workon and adjacent concave, convex.and Otherwise irregular. surfaces, not possible with a plane stock having the usual continuous face of uniform width.

Changes in detail of construction will be obvious Vtothose skilled in the art and may be made within scope and spirit of the foregoingspecification and the appended claims.
